Complete and quantitative, NAPL Removal: Surfactants, Foams, and Microemulsions, belongs to a ten-monograph series that records the results of the Department of Defense/Advanced Applied Technology Demonstration Facility environmental technology demonstrations. It presents the outcome of field demonstrations of innovative in situ remediation technologies. In situ surfactant and cosolvent flushing for nonaqueous phase liquids constitutes a technique with the potential to reduce the mass of NAPL - a continuing source of groundwater contamination. This monograph details two technologies - surfactant/foam and single-phase microemulsion - selected for their potential to address the needed breakthroughs. Copiously illustrated with figures and tables, NAPL Removal: Surfactants, Foams, and Microemulsions takes you through the entire field demonstration step-by-step. It describes the development of the processes, analyzes the costs, discusses design issues, and covers performance and potential application.

A $19.3 million Department of Defense grant to Rice University funds the Advanced Applied Technology Demonstration Facility (AATDF). One of the project goals is the development of reduction strategies for nonaqueous phase liquids (NAPLs) in the subsurface. Surfactants and Cosolvents for NAPL Remediation records the results of AATDF research. The manual is a guide to the practical application of surfactants/cosolvent for in situ remediation. It is targeted to decision makers and anyone concerned with the design or implementation of these technologies. The book discusses the situational viability of surfactants/cosolvents , the possible results, design, and operation. It includes case studies, step-by-step guidance, and project cost work sheets. The successful results of the AATDF research, as documented Surfactants and Cosolvents for NAPL Remediation, are an invaluable contribution to the future of subsurface remediation. Without source NAPL reduction, the alternative is decades of plume management through pump-and-treat.

A part of the continuing effort to provide innovative in situ remediation techniques, Remediation of Firing-Range Impact Berms presents the results of a soil washing and leaching project. The demonstration set as its primary objective providing reliable, detailed performance data to evaluate the feasibility and cost of implementing a full-scale system. Its secondary objective was to demonstrate the effectiveness of the technology in producing a 'clean' soil based on analytical results. The project included the following steps: Bench scale treatability studies of prospective soils Selection of a demonstration site Pilot plant equipment design, installation, and shakedown Execution of the demonstration at the selected DOD site Preparation of the Final Technical Report (FTR) and the Technology Evaluation Report (TER) The monograph discusses the results of the pilot plant study and includes the technical information necessary to reproduce the study full-scale. It recommends procedures for successful soil washing at small arms ranges. Remediation of Firing-Range Impact Berms will save you time and money when using in situ technology for soil remediation.

One of the most widely used techniques for treating soils contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOCs) if the soil is heated, by applying electromagnetic energy in the radio frequency (FR) range, to increase the vapor pressure of the contaminants. Although RF-SVE systems used in previous field demonstrations have had varying degrees of success, questions remain concerning its viability and cost-effectiveness. Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration covers detailed scientific and engineering information that answers these questions. The book includes the necessary databases, equations, and example calculations for RF heating. The theoretical and practical information included will facilitate future testing of RF-SVE treatment of soils. Additionally, the book provides information for a full-scale engineering design of potential RF-SVE applications. The authors use this information to examine predicted performance, magnitude of costs, and modifications to the design that may decrease cost. Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration gives an economic analysis of this innovative technology and considers other possible applications for it.

Modular Remediation Testing Systems documents a unique modular testing environment designed for use in the development of remediation technology and for on-site selection of remedial technologies. This complete design and operation manual gives you the tools you need to conduct successful, cost effective remediation projects. The major attributes of this system, the Experimental Controlled Release System (ECRS), that distinguish it from past test facilities include the following: Portable - shippable to the researcher's location or remediation site Tightly sealable - facilitates mass balance Large pilot-scale facility - step below full-scale demonstration Flexible testing conditions - vadose zone or aquifer, chemical release or contaminated soil, air sparging or SVE Easy to construct - design drawings developed, standard equipment Easy to operate and maintain - easy access, standard equipment Affordable - easily shipped and set up, reduced regulatory requirements, minimal maintenance Faster tests - reduced or eliminated permitting, operate within one week of arrival, programmable for 24-hour duration This monograph presents key information needed to design, construct, and operate similar modular remediation testing systems or to utilize the two existing modular ECRS facilities. The well-sealed, above-ground modular system design minimizes leaks to the environment, facilitates mass balances, and controls test conditions. This allows for multiple uses with minimal permitting. Modular Remediation Testing Systems is a comprehensive reference for researchers in environmental engineering and for engineering consultants and regulators looking for a pilot-scale system. These pilot-scale systems are uniquely suited to both research development and real-world application at remediation sites.

Chlorinated Solvent and DNAPL Remediation addresses remediation of chlorinated solvents and dense nonaqueous phase liquids (DNAPLs) in groundwater and discusses remedial alternatives that are available for subsurface cleanup. Chlorinated Solvent and DNAPL Remediation: Innovative Strategies for Subsurface Cleanup focuses primarily on current technological developments and innovative applications for in situ remediation of chlorinated solvents including DNAPLs in soil and groundwater. However, this book also provides a general overview of all of the physical, chemical, and biological processes available for in situ remediation of groundwater contaminated with chlorinated solvents and DNAPLs. Chapters discuss surfactant flushing to enhance DNAPL removal; in situ chemical destruction by reduction processes involving zero valent iron or related metals; in situ chemical destruction by advanced oxidation processes; and in situ biological destruction by enhanced anaerobic bioremediation or natural bioattenuation. This book also emphasizes zero valent iron-based strategies, including reaction geochemistry, permeable reactive barrier longevity, rejuvenation of iron walls, and emplacement technique. One chapter summarizes 10 years of permeable reactive barrier development and application. The controversial issues related to DNAPL remediation, including the concept that remediation of sites affected by DNAPL could be technically impractical, are reviewed. Another chapter focuses on the evolution of DNAPL remediation practice.
